A complete assembly, identified as PK-520, facilitates the creation of precise openings in various materials. This toolset typically includes a selection of punches, dies, and the necessary driving mechanism, often a hand-operated or hydraulic press. An example application is in electrical panel fabrication, where it enables the clean creation of holes for wiring and components.
The utilization of such a kit offers several advantages, including improved accuracy and consistency compared to manual methods such as drilling. It minimizes material deformation and burring, resulting in a professional finish. Historically, these kits have evolved from simple, manually operated devices to more sophisticated hydraulic systems, reflecting advancements in manufacturing and materials science.
